THREE DIMENSIONAL IMAGE RECONSTRUCTION FROM SINGLE PLANE X-RAY FLUOROGRAMS

A method is provided to reconstruct the three-dimensional image of an X-ray contrast agent-filled object having at least one plane of symmetry using a single plane two-dimensional X-ray projection. The projection is obtained by irradiating the object with X-rays substantially perpendicular to a selected plane of symmetry of the object. The absorbance value of each pixel in the projection, which is related to the distance travelled by the X-ray within the object, is then divided by 2 to define the z coordinates on each side of the x-y plane of symmetry of the object. The z coordinates together with the x,y coordinates of each pixel define the three-dimensional contour of the object.
